Abilities: Diamondback is an Olympic level athlete who excels in gymnastics, an accomplished hand-to-hand combatant, and expert thrower of knives and other sharp objects.

Weapons: Diamondback wields an undisclosed number of 4-inch long elongated diamond-shaped throwing spikes. She refers to these weapons as "diamonds," even though they are not made of actual diamond (which would be far too expensive for use). Stored in her boots and gloves and possibly elsewhere on her costume, these diamonds are needle-sharp and sometimes filled with various substances. Known diamonds in her arsenal have contained a lethal fast-acting snake venom-derived poison, an impact-detonated explosive with the concussive force of 10 pounds of TNT, a highly corrosive concentrated hydrochloric acid, and a fast-acting sleep-inducing narcotic.
